Tagging Oracle ACFS File Systems

This section discusses the operations to manage tagging on directories and files in an Oracle ACFS file system on Linux.

The disk group on which the volume is created for the file system has compatibility attributes for ASM and ADVM set to 11.2.0.3 or higher. For information about disk group compatibility, refer to "Disk Group Compatibility".

Oracle ACFS implements tagging with Extended Attributes. There are some requirements for using Extended Attributes; refer to "Oracle ACFS Tagging".

The steps to manage tagging are:

Specify tag names for directories and files.

Run the acfsutil tag set command to set tags on directories or files. You can use these tags to specify which objects are replicated.

For example, add the comedy and drama tags to the files in the subdirectories of the /acfsmounts/repl_data/films directory.
```
$ /sbin/acfsutil tag set -r comedy /acfsmounts/repl_data/films/comedies

$ /sbin/acfsutil tag set -r drama /acfsmounts/repl_data/films/dramas

$ /sbin/acfsutil tag set -r drama /acfsmounts/repl_data/films/mysteries
```
In this example, the drama tag is purposely used twice and that tag is changed in a later step.

You must have system administrator privileges or be the file owner to run this command.

For more information, refer to "acfsutil tag set".
Display tagging information.

Run the acfsutil tag info command to display the tag names for directories or files in Oracle ACFS file systems. Files without tags are not be displayed.

For example, display tagging information for files in the /acfsmounts/repl_data/films directory.
```
$ /sbin/acfsutil tag info -r /acfsmounts/repl_data/films
```
Display tagging information for files with the drama tag in the /acfsmounts/repl_data/films directory.
```
$ /sbin/acfsutil tag info -t drama -r /acfsmounts/repl_data/films
```
You must have system administrator privileges or be the file owner to run this command.

For more information, refer to "acfsutil tag info".
Remove and change tag names if necessary.

Run the acfsutil tag unset command to remove tags on directories or files. For example, unset the drama tag on the files in the mysteries subdirectory of the /acfsmounts/repl_data/films directory to apply a different tag to the subdirectory.
```
$ /sbin/acfsutil tag unset -r drama /acfsmounts/repl_data/films/mysteries
```
Add the mystery tag to the files in the mysteries subdirectory of the /acfsmounts/repl_data/films directory.
```
$ /sbin/acfsutil tag set -r mystery /acfsmounts/repl_data/films/mysteries
```
You must have system administrator privileges or be the file owner to run these commands.

For more information, refer to "acfsutil tag unset".
